AP physics C suggestions..........thanx!I have signed up for both AP Physics C Mech exam and E&M exam. Now I found that I don't have enough time to study for both exams (2 days left), should I give up E&M and focus on Mech? I felt that E&M is not harder than Mech, but need to remember many equations, which I can't...

chemistryin dealing with alcohol mechinisms, how do you know when to do dyhydration (elimination) or substitution? is it secondary and teritary undergo both Sn1 & E1 and primary undergo Sn2 and E2. or is one mech actually preferred? it seems like H2SO4 is always dehydration.
